A. 
Location. Dispensing devices at automotive service stations shall be so located that all parts of the vehicle being served will be on the premises of the service station. All gas tanks should be buried with a two-foot ground cover. They can be aboveground over 2,500 gallons, with proper fill. Tanks must meet Interstate Commerce Commission over-the-road requirements.
(1) 
Inside location. Approved dispensing units may be located inside garages upon specific approval of the Building Inspector and the Chief of the Fire Department or fire companies as designated under § 113-5. The dispensing area shall be separated from motor vehicle repair areas in a manner approved by the Building Inspector and the Chief of the Fire Department. The dispensing unit and its piping shall be protected against physical damage from vehicles either by mounting on a concrete island or by equivalent means and shall be located in a position where it cannot be struck by a vehicle descending a ramp or other slope out of control. The dispensing area shall be provided with an approved mechanical or gravity ventilation system. A clearly identified switch, readily accessible in case of fire or physical damage to any dispensing unit shall be provided to shut off the power to dispensing units. When the dispensing units are located below grade, only approved mechanical ventilation shall be used and the entire dispensing area shall be protected by an approved automatic sprinkler system. The ventilating systems shall be electrically interlocked with the gasoline dispensing units so that the dispensing units cannot be operated unless the ventilating fan motors are energized. On all service stations which are temporarily closed or abandoned, all lights, pumps and signs are to be removed; doors and windows shall be boarded up; driveways shall be roped off with markers every six feet; all underground tanks shall be filled with water or sand and locks shall be placed on the filling inlet or riser or removed completely.
B. 
Class I and Class II flammable liquids.
(1) 
Class I and Class II flammable liquids shall be transferred from underground tanks by means of fixed pumps so designed and equipped as to allow control of the flow and to prevent leakage or accidental discharge. Class I or Class II flammable liquids shall not be transferred from any storage tank by any equipment or procedure which subjects the shell of the storage tank to pressures above its allowable working pressure. Air or gas pressure shall not be used for this purpose.
(2) 
Supplemental means shall be provided outside of the dispensing device whereby the source of power may be readily disconnected in the event of fire or other accident.
(3) 
Dispensing devices for Class I or Class II flammable liquids shall be of an approved type.
(4) 
Class I and Class II flammable liquids shall not be dispensed by pressure from drums, barrels or similar containers. Approved pumps taking suction through the top of the container or approved self-closing faucets shall be used.
C. 
Automatic dispensing units. The installation and use of coin-operated dispensing devices for Class I flammable liquids is prohibited.
D. 
Automatic nozzles with latch-open devices. In lieu of being held open by hand, an approved automatic nozzle may be used for dispensing Class I flammable liquids into the fuel tank of a vehicle. Such a nozzle shall have the latch-open device as an integral part of the assembly and shall shut off the liquid reliably and positively when the gasoline tank is filled, when it falls from the filling neck of an automobile tank, when it is subject to rough usage, such as dropping or lack of proper lubrication, or when an automobile is driven away while the nozzle is still in the tank. A competent attendant shall be in the immediate vicinity of the vehicle being filled by such an approved nozzle.
E. 
Manual nozzles. A manual nozzle without an automatic shutoff device is prohibited in the dispensing of Class I or Class II flammable liquids into the fuel tank of a vehicle or into a container.
F. 
Dispensing containers. No delivery of any Class I or Class II flammable liquids shall be made into portable containers of five-gallon capacity or less unless the container is of sound metal construction, has a tight closure with screwed or spring cover and is fitted with a spout or so designed that the contents can be poured without spilling.
G. 
The dispensing unit and its piping, except that attached to containers, shall be mounted on a concrete island or protected against collision damage by suitable means. If located indoors, the dispenser shall also be mounted either on a concrete island or protected against collision damage by suitable means and shall be located in a position where it cannot be struck by a vehicle that is out of control descending a ramp or other slope.

H. 
If operations are normally conducted during other than daylight hours, adequate lighting shall be provided to illuminate containers being loaded, control valves and other equipment.
